Interest of pelvic and paraaortic lymphadenectomy in patients with stage IB and II cervical carcinoma.

OBJECTIVES: The objectives of this study were to evaluate the interest and the potential therapeutic value of systematic pelvic and paraaortic lymphadenectomy in patients with stage Ib and II cervical carcinoma. METHODS: This was a prospective study including 421 patients with cervical cancer treated, from 1985 to 1994, by combined radiation therapy and surgery with systematic pelvic and paraaortic lymphadenectomy. RESULTS: The overall rate of pelvic lymph-node involvement was 26% (106 patients), and the rate of paraaortic metastases was 8% (32 patients). Pelvic nodal involvement was unilateral in 14% (59 patients) and bilateral in 11% (47 patients). Macroscopic positive nodes were found in 12% (52 patients). In a univariate analysis, a young age (<30 years), a tumor size >/=4 cm, stage II disease, and nodal involvement were associated with significantly decreased survival. The nodal status and the characteristics of positive nodes (number and location) were the most significant prognostic factors. In the multivariate analysis, age, the tumor size, and the site of nodal involvement (pelvic or paraaortic) were prognostic factors. Three-year survival was 94% for patients with negative nodes compared to 64% for patients with positive pelvic nodes and 35% for patients with positive paraaortic nodes (P < 0.0001). CONCLUSION: These results confirm the diagnostic and prognostic value of systematic complete lymphadenectomy when planning adjuvant treatment and the therapeutic value of complete removal of bulky positive nodes.

Laparoscopic ovarian transposition for pelvic malignancies: indications and functional outcomes.

OBJECTIVE: To assess the indications and effectiveness of laparoscopic ovarian transposition before pelvic irradiation for a gynecologic cancer. DESIGN: Prospective study. SETTING: A gynecologic oncology department in a French anti-cancer center. PATIENT(S): Twenty-four patients treated for pelvic cancer. INTERVENTION(S): Laparoscopic ovarian transposition to paracolic gutters. Uterine conservation in 18 patients. MAIN OUTCOME MEASURE(S): Clinical and laboratory follow-up tests of ovarian function. RESULT(S): Bilateral laparoscopic ovarian transposition was achieved in 22 patients (94%). Twelve patients were treated for clear cell adenocarcinoma of the cervix and/or upper vagina, 6 patients for invasive squamous cervical carcinoma, 3 patients for pelvic sarcoma, 1 patient for recurrent cervical cancer to the upper vagina, 1 patient for ependymoma of the cauda equina, and 1 patient for ovarian dysgerminoma. Ovarian preservation was achieved in 79%. Three pregnancies were obtained. CONCLUSION(S): Laparoscopic ovarian transposition is a safe and effective procedure for preserving ovarian function. Bilateral ovarian transposition should be performed. The main indications for laparoscopic ovarian transposition are a patient with a small invasive cervical carcinoma (<2 cm) in a patient <40 years of age who is treated by initial laparoscopically assisted vaginal radical hysterectomy and a patient with a clear cell adenocarcinoma of the cervix and upper vagina.

Tumour size in cancer of the cervix.

In a randomized trial comprising 204 patients with operable cervical carcinomas stages I and II, two low-dose rates in gynaecological brachytherapy were compared. Treatment consisted of Cs-137 uterovaginal application followed by surgery (either immediate or delayed). The results for the two dose rates have been published previously. The present paper concerns the correlation between outcome and tumour size. Tumour size was carefully estimated in two ways: by clinical examination under general anaesthesia and by measurements on the customized vaginal mould used for the brachytherapy. Ninety-one patients (45%) were classified as stage I, and 113 were classified as stage II proximal. The mean tumour size was 39 mm (range 15-64 mm). Cox's multivariate analysis indicated that the factors with a poor prognostic value were for survival: node involvement (N +) (p < 0.001), large tumour size (T +) (p < 0.001) and involvement of the endocervix (E +) (p <0.01); for event-free survival: N + (p <0.001), T + (p < 0.001); for local control; N + (p = 0.0001); for metastasis and regional relapse: N + (p < 0.001) and T + (p < 0.001). Stage was not a prognostic factor over the present range in either univariate or multivariate analysis. In this series tumour size is a powerful independent prognostic factor. It is therefore suggested that for the classification of cervical cancer and the indications for surgical staging and adjuvant treatment, tumour size should be taken into account.

Fertility results after ovarian transposition for pelvic malignancies treated by external irradiation or brachytherapy.

The aim of this study was to assess the fertility outcome after ovarian transposition with uterine conservation and pelvic irradiation therapy for pelvic cancer. A total of 37 consecutive cases were reviewed. Of these, 27 patients were treated for a clear cell adenocarcinoma of the vagina and/or the cervix (group 1), nine for an ovarian pure dysgerminoma and one for a para-uterine soft tissue sarcoma (group 2). The pregnancy rate was 15% (4/27) in group 1 and 80% (8/10) in group 2 (P=0.01). A total of 18 pregnancies was observed in 12 patients. Of these, 16 pregnancies were obtained spontaneously and two after in-vitro fertilization. Of the spontaneous pregnancies, 12 (75%) were observed with ovaries still in the abdominal cavity (not repositioned). These results show that the prognosis for fertility is excellent after ovarian transposition and irradiation in patients with morphologically normal genital tracts (group 2). The prognosis is not as good for patients treated for a clear cell adenocarcinoma of the vagina and/or the cervix who may have morphological and/ or functional anomalies of the genital tract, following exposure to diethylstilboestrol and brachytherapy (group 1). Furthermore, these results show that repositioning of the ovary is not essential to achieve pregnancy.

Adenocarcinoma, Clear Cell

[Carcinoma of the endometrium: review of the literature].

In endometrial adenocarcinoma, many risk factors have been demonstrated. Among them, tamoxifene is a factor of low risk. Any endometrial bleeding requires a gynecological exam in order to make an early diagnosis. The positive histologic diagnosis is more often after surgery which is necessary for histo-prognostic stage. Non conservative hysterectomy with pelvic lymphadenectomy (obturator chain) is recommended for the most frequent stages I and II. Radiation therapy alone is recommended for stage III. Palliative therapy (hormonotherapy or chemotherapy) could be proposed for the few stage IV.

Squamous cell carcinoma of the penis: multivariate analysis of prognostic factors and natural history in monocentric study with a conservative policy.

BACKGROUND: Penile carcinoma is uncommon in Western countries. Here we report on a large series of patients with squamous cell carcinoma (SCC) of the penis, describing prognostic factors, survival and therapeutic results. PATIENTS AND METHODS: From 1973 to 1993, 102 patients with invasive SCC of the penis were treated at the Institut Gustave-Roussy. Precancerous lesions and conditions associated with penis cancer were analyzed retrospectively. Survival curves were estimated by the Kaplan-Meier method, and groups were compared for outcome by the log rank test for univariate comparisons and by Cox's proportional hazards model for multivariate analysis. RESULTS: The median age at onset was 58 years. Sixty-nine patients presented with Jackson's stage I disease, 17 with stage II and 15 with stage III. The interval between the manifestation of symptoms and the diagnosis was more than a year in 13.7% of cases. Precancerous lesions were found in 17 (16.6%) patients, and a history of phimosis was noted in 25 (24.5%). In situ and invasive carcinoma were observed together in 17 (16.6%) cases and dysplasia was associated with invasive carcinoma in eight (7.8%) further cases. Conservative treatment was administered whenever feasible. Interstitial brachytherapy was performed alone or associated with limited surgery (local excision or circumcision) in 72 (70.6%) patients. Of the 28 patients with a local relapse, nine have died of their neoplasms (32%) compared to 21 of 28 patients with lymph node relapse (75%). The median follow-up was 111 months. Disease-free survival, disease-specific survival and overall survival were, respectively, 56%, 72% and 63% at five years and 42%, 66% and 50% at 10 years. Age (P = 0.01), the N status (P < 0.00001) or palpable nodes (P < 0.0038), corpus involvement (P = 0.006) and a verrucous histology (P = 0.038) had significant prognostic relevance for survival in the univariate analysis whereas the performance status, T status and Broders' grade did not. In the multivariate analysis only two parameters, involvement of the corpus (P < 0.0001) and palpable nodes (P = 0.009), were singled out as being independent variables influencing survival. A subgroup of nine patients with verrucous histologies were distinguished by their freedom from node involvement. These patients had an excellent prognosis: all are alive and disease-free. Penile integrity was preserved during follow-up in 54 patients (52.9%), 31 of whom are still alive. Of 72 patients treated by a conservative approach including brachytherapy, long-term penile integrity was maintained in 49 (68%). CONCLUSION: Corpus involvement and clinically palpable nodes are highly statistically significant independent factors influencing overall survival. Node relapses remain a major cause of death. Thus, better management of lymph nodes is essential for improving survival even when conservative therapy is used to treat the primary.

[Negative second-look laparatomy in ovarian cancers. Survival analysis and prognostic factors from 64 cases treated at the Gustave Roussy Institute].

This study describes 64 cases of ovarian adenocarcinoma seen in the Gustave-Roussy Institut between 1978 and 1988 and who had a negative second-look laparotomy. The median age was 51 years (30-74). FIGO stages were: I: 7 (11%); II: 3 (5%); III: 39 (61%); IV: 3 (5%); and undetermined: 12 (19%). There were 53% of serous type, 14% of endometrioid type, 13% of undifferencied type, 8% of clear cells type, 3% of mucinous type, and 9% of mixed type tumors. There were 50% of grade 3 tumors. Initial debulking surgery was as complete as possible in 59 patients, with a residual tumor after surgery superior or equal to 2 cm in 25 patients. Post second-look surgery treatment (n = 57) consisted of chemotherapy (CT) alone in 22 patients (34%), radiotherapy (RT) alone in 31 patients (49%), and CT associated with RT in 4 patients (6%). Median follow-up is 100 months. The overall survival rates at 3 and 5 years were respectively 86 and 81%, and disease free survival rates 70 and 61%. Among the 64 patients, 26 relapsed (39%). Median time to relapse was 96 months. There is a statistical difference in the survival between patients who had no or inferior to 2 cm residual tumor and others. Residual tumor was the only factor to be significant in univariate and multivariate analysis of survival.

Clinical applications of proton therapy.

Proton therapy offers considerable potential advantages in the management of poorly resectable, radio-resistent tumors close to critical anatomical structures. So far over 15,000 patients have been treated worldwide with two major indications: conservative management of ocular melanomas in which local control exceeds 95% at 5 years and curative irradiation of sarcomas at the base of the skull and cervical canal, with a survival rate between 84 and 94% at 5 years. The different protocols tested currently worldwide are discussed.

Non-parametric methods for analysing recurrent complications of varying severity.

Non-parametric methods have recently been proposed to take into account the recurrent nature of complications in clinical trials, by estimating the prevalence Q(t), defined as the probability of relapse-free patients being in a complication state at time t. Recoveries are also considered. These methods have been adapted in this paper to take into consideration not only the recurrent nature of complications but also their severity through the interpretation of average weight functions. Results of a randomized trial comparing late complications following two alternative doses of pre-operative internal brachytherapy in patients with localized stage cervix carcinoma are used to illustrate the methods.

[Conformal radiation therapy. Fédération nationale des centres de lutte contre le cancer (FNCLCC)].

The authors present the summary of a workshop of a group of radiation oncologists and radiation physicists on three dimensional treatment planning and conformal radiation therapy with multileaf collimator. It appears that this technic must be considered as experimental and that it cannot be promoted in all radiotherapy departments without scientific and clinical evaluation.

Evaluation Studies as Topic

[Role of radiotherapy in the treatment of meningioma].

Between 1962 and 1986, 32 patients with intracranial meningiomas were referred to the Institut Gustave-Roussy for external radiotherapy either after incomplete surgery, or unfavorable histology (meningiosarcoma/anaplastic meningioma), or after recurrences. In the latter case, the mean time interval between the first surgery and the recurrence was 2 years (range: 1-6 years). Radiotherapy was performed using photons, electrons or mixed photons-electrons. The mean total dose was 48 Gy (range: 9-65 Gy) delivered in a mean time of 35 days with a 19 mean number of fractions. Radiotherapy was interrupted in three cases at 9 Gy-17 Gy-20 Gy because of neurological worsening. The actuarial 5-year survival was 64%. Among the 32 patients, 11 died, eight of tumoral progression or recurrence and three of other causes (one ovarian carcinoma, two unknown). Among the 21 alive patients, eight presented a recurrence; five of them could be reoperated on with two complete resections. None of the following factors were found to be of prognostic value on the survival nor on the recurrence occurrence: age, tumor location, first surgical resection type, and, in the group of patients treated at the time of recurrence, the quality of the surgery at the time of recurrence and the time interval between the first surgery and the recurrence. Only one factor was evidenced as of significant value on the recurrence as well as the 10-year survival: the total dose of irradiation with a 10-year survival rate of 74% for total doses higher than or equal to 47 Gy versus 14% when the total dose was lower than 47 Gy.

Multivariate analysis of prognostic factors in adult patients with medulloblastoma. Retrospective study of 156 patients.

BACKGROUND: Medulloblastoma is a rare disease in adult patients, with an annual incidence rate of 0.05 per 100,000 per year. Results are, therefore, sparse and comprise small series over long periods. The real survival rate, the prognostic factors, the optimal postoperative radiation dose, and the role of adjuvant chemotherapy are still unknown for this disease in adults. METHODS: The authors collected 156 cases of histologically proven medulloblastoma in patients older than 18 years of age who were treated between January 1975 and December 1991 in 13 French institutions. They analyzed the prognostic factors for survival and the impact of postoperative treatment on survival. RESULTS: The 5- and 10-year event free survival rates, 61 and 48%, respectively, are similar to those observed in children. The median time to recurrence is 30 months, but late relapses after 5 years remain frequent. Multivariate analysis identified postoperative performance status, spinal axis radiation dose, fourth ventricular floor involvement, and desmoplastic histologic subtype as factors significantly correlated with event free survival. No benefit of concomitant chemotherapy was demonstrated, and complete resection resulted only in severely reduced postoperative performance status. CONCLUSIONS: The prognostic factors in adult medulloblastoma are comparable to those of medulloblastoma in children, but a new parameter, postoperative performance status, was identified in this adult series. Postoperative craniospinal irradiation remains the standard treatment for adults with medulloblastoma. A reduced dose to the supratentorial compartment should be tested in a prospective protocol.

Analysis of complications in a prospective randomized trial comparing two brachytherapy low dose rates in cervical carcinoma.

PURPOSE: The analysis of complications in a prospective randomized trial comparing two preoperative brachytherapy low-dose rates in early stage cervical cancer is presented. METHODS AND MATERIALS: Between 1985 and 1988, 204 patients with Stage I and limited Stage II cervical cancer were randomized to receive one of two preoperative brachytherapy low-dose rates (0.4 and 0.8 Gy/hr). The objective of this trial was to determine the benefits, if any, of the higher-dose rate within the therapeutic arsenal for this patient population, in terms of survival, local control, and complications. The type and severity of all complications were evaluated according to a common glossary and a strict follow-up schedule was established given that the treatment of cervical cancer is multidisciplinary, involving gynecologists, surgeons, and radiotherapists. RESULTS: Overall survival: 85% at 2 years and local control: 93% at 2 years, were similarly distributed between the two groups. Regardless of their nature and severity, 139 and 175 complications were observed among 63% and 75% of patients, in the 0.4 and 0.8 Gy/h dose rate groups respectively. Gynecologic and urinary complications were the most frequent (38% and 28% of all complications), followed by vascular (15%), digestive (10%), nervous (5%) and cutaneous (5%). A total of 14 and 17 severe complications (Grade 3) were observed in 7% and 13% of patients, respectively in the 0.4 and 0.8 Gy/h dose rate groups (p = 0.12). Nonparametric survival methods used to compare the time to the first complication did not show a significant difference between the two groups: 62% and 72% at 2 years (p = 0.27). When the first complication and its evolution were considered (early complications), the prevalence of complications was not significantly different between the two groups: 28% vs. 34% at 2 years (p = 0.31). In this prospective trial, patients were regularly followed-up and complications of varying nature and severity were observed in succession during follow-up. When successive complications and their evolution were taken into account, the prevalence of complications was significantly greater in the higher-dose rate group: 30% vs. 45% at 2 years (p = 0.03). CONCLUSION: The results of this trial showed that long-term effects of treatment, when represented by prevalence of complications over time, were more frequent in the higher dose rate group. This underlines the importance of the regular follow-up of patients and of coding, not only the occurrence of all complications, but also their evolution over time.
